I have the same issue. I'm unable to create a new post as this is getting flagged for sensitive content. Not sure what could be causing this. Dear Apple Support Team, I’m reaching out for help with implementing Sign in with Apple for my web application. While I’ve successfully integrated it into my Capacitor iOS app, I’m encountering issues with the web version: Chrome/Edge: Persistent invalid_client error (tested with both usePopup: true/false). Safari (Mac): The sign-in popup appears, but after login, it shows "Signup Not Completed." Configuration Details: Frontend: https://dev.mydomain.com (served via Cloudflare tunnel). Backend: https://dev-api.mydomain.com. Apple Developer Portal: Configured Service ID (not bundle ID). Added domains/subdomains: dev.mydomain.com, dev-api.mydomain.com. Redirect URIs: Frontend: https://dev.mydomain.com/apple-callback (for JS SDK listener). Backend: https://dev-api.mydomain.com/oauth/callback/apple (for token handling). Steps Taken: Verified Service ID and configuration multiple times. Waited 48+ hours for DNS/propagation (per community suggestions). Tested various redirectURI combinations. This issue is blocking my progress, and I’d greatly appreciate any guidance to resolve it. Let me know if additional details are needed.
